SPORTS PEOPLE: FOOTBALL;Tagliabue Set to Decide on Irvin

National Football League Commissioner PAUL TAGLIABUE will decide this week on what disciplinary action, if any, to take against the Cowboys' MICHAEL IRVIN, who has pleaded no contest to drug possession.

Tagliabue, visiting the Jets yesterday at the opening of their summer camp in Hempstead, L.I., said he could rule "from no action to a wider degree." He pointed out that in many previous cases players who admitted to Irvin's type of crime received four-game suspensions.

However, Tagliabue said that recent rulings that involved off-season behavior also allowed the player to compete during the exhibition season. Suspensions would start when the regular campaign began. He did not say, though, that this would be his ruling on Irvin.
